Which of the following best describes software?

Software refers to the collection of programs and instructions that tell a computer how to perform specific tasks. This includes everything from operating systems, which manage the computer's hardware and software resources, to applications that enable users to perform tasks like word processing or web browsing. Software is intangible and exists as code, distinguishing it from hardware, which encompasses the physical components of a computer. Understanding software as the set of instructions rather than any physical or design aspects helps clarify its critical role in the functionality of a computer system. The other choices relate to physical elements or aspects of electricity and design, which do not encompass the definition of software.
